This is a bit off topic but this thread has brought back memories of the things I put myself through when I had just started playing games. Three games in particular: the original Final Fantasy, Castlevania II and Faxanadu. I beat all three of these games as I'm sure many others have but just think about what a feat that was back then.
In the original, unaltered, NES version of Final Fantasy there was all kinds of [censored] you had to contend with. You could only save by sleeping at an inn or using a tent so dying in a dungeon usually meant losing an hour's worth of progress or more. And since you couldn't save in a dungeon, if you had to suddenly go somewhere (my gaming sessions were often interrupted by church

) you either left your nintendo running or you lost all your progress. And then there was the whole issue of characters attacking and missing a target because it was already dead. They weren't smart enough to attack something else back then. Not to mention the hours upon hours of grinding with that particular version.
Castlevania II and Faxanadu had similar setups. Progress involved constantly writing down passwords since battery backup wasn't around yet. Well it was by the time I got around to playing them but that didn't change things. Castlevania II had a couple of [censored] you moments where the only possible way you'd know how to procede was through a game guide. Or in my case a friend who had already beaten it. And Faxanadu's idea of level progression was increasing the amount of money you start with when you die.
And aside from all of these issues, all three of these games were just painfully difficult by there very nature. As much fun as I had, looking back I'm amazed I had the patience enough to play them all the way through. And in the case of Final Fantasy I did that three or four times.
